Consider the possibilities for this dashboard. It could be updated to report by status (vulnerabilities.status: [NEW,ACTIVE,REOPENED,FIXED]), or patchable vs. configuration (vulnerabilities.vulnerability.patchAvailable: TRUE/FALSE). For examples of widgets using these tokens, please visit Dashboard Toolbox - Top 10 Vulnerabilities Scorecard BETA.

When you export dashboard(s) and/or widget(s) that have "Enable historical data collection" turned on, and then import them later, you will have to manually "Enable historical data collection" following your import. This is by design. The action of turning on this feature starts the clock for data retention.
